SYNTHESIS AND RED EMISSION OF Eu3+ DOPED NaLaMo2O8 PHOSPHORS
Abstract
Eu3+ doped NaLaMo2O8 phosphors were synthesized by a conventional solid state reaction. The phase and luminescent properties of the synthesized phosphors were investigated in the current work. In NaLaMo2O8, Eu3+ ions replace La3+ ions and form solid compound. This substitution induces the 2θ angles of diffraction peaks to shift to larger values. Under excitation at 395 nm, NaLaMo2O8:Eu3+ phosphors exhibit emission bands in the range of 550-725 nm originating from 5D0®7FJ transitions (J = 0, 1, 2, 3, 4) of Eu3+ . The strongest emission band corresponds to the 5D0®7F2 transition, which indicates a site of Eu3+ without inversion symmetry in NaLaMo2O8. The Eu3+ concentration has obvious influence on the luminescent properties of NaLaMo2O8:Eu3+ phosphors. NaLaMo2O8:6mol%Eu3+ has the strongest excitation and emission intensities.
